LUBRICATOR.

Patented Nov. 20, 1906.

Application filed January 17,1906. Serial No= 296,514=.

To all whom it may concern.-

Be it known that we, EDGAR C. MATSON and EDWIN J. BALDWIN, citizens of the United States, residing at Harriman, in the county of Roane and State of Tennessee, have in vented certain new and useful Improvements in- Lubricators; and we do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to lubricators for journal-bearings, such as those ordinarily employed in the j ournal-boxes for car-axles, although it is obvious that it is not limited to that use.

The object of the invention is to provide means for constantly pressing the lubricating-block against the under side of the ournal, and this object is carried out by use of springs whereby the block is drawn constantly upward with a gentle pressure against the lower side of the bearing.

In the accompanying drawings, forming part of this specification, Figure 1 is an end view of the device with the walls of the box and the receptacle in section. Figs. 2, 3, 4, and 5 are details showing some of the many forms of attachment between the supporting rods and receptacle; and in Fig. 5 is illustrated how side springs might be employed in any of these constructions.

Referring to Fig. 1 of the drawings, the letter B designates the box, and J the journal. Above the latter is the wear-plate or brass W, usually employed in this type of journalbearings to support the superimposed weight, this brass being held in place by any suitable member and preferably made removable, so that it can be replaced when worn.

Within the box beneath the ournal is inserted a receptacle R of proper shape to contain a block P, of lubricating material, which block is grooved in its upper face so as to fit beneath and extend partially around the under side of the ournal. The receptacle R is drawn constantly upward by springs, whereby the block is held in contact with the under side of the journal as it wears away in use.

Although the shape of the block will ordi narily hold it in proper position beneath the journal, we may in some instances provide side or lateral springs L, which by preference are riveted to the sides of the receptacle B and bear against adjacent sides of the box B, thereby centering the block laterally beneath the journal. It will be understood, of course, that the flanges on the ournal itself will center the block longitudinally beneath it without the necessity for further mechanism.

In order that ready access may be had to the springs and their proper operation may be observed, we locate them above and outside the box B, and the receptacle R is supported by truss-rods T, connected with it and leading thence upward through the top of the box to a cross-piece C, which rests upon the springs. These rods have nuts N at their upper ends, whereby the tension of the springs can be adjusted and the receptacle and block drawn more forcibly upward when desired. The lower ends of these rods may be connected with the receptacle in a variety of ways. In Fig. 1 they pass through ears E on the receptacle and have nuts T at their lower ends within the box.

In Fig. 2 these nuts are replaced by split pins T In Fig. 3 the lower ends of the rods are bolted, as at T directly to the receptacle, the nuts being by preference on the outside, so that they can be removed and in Fig. 4 the two rods T are continued around beneath the box, as at T and united into one supporting rod or bail. In Fig. 5 the rod has a head T at its lower end, and the ear E has a notch E, into which the rod may be passed from the outside. This view also shows how the lateral or side springs L could be used in any ofthese constructions.

When the lubricating-block becomes much worn, the entire receptacle is depressed by hand and removed longitudinally from the box, a new block inserted, and the parts restored to their original. position. The thickness of this new block will compress the springs S, as required. No details of the component parts of the block are stated in this patent, as it is only necessary here to specify that the block must be of such material that as it wears away it shall afford a constant lubrication to the journal.

What is claimed as new is-- 1. In a lubricator, the combination with the j ournal-box, and a lubricating-block; of a receptacle for the block fitting loosely within the box, means for centering it laterally therein, springs resting upon the box, and rods supported by the springs and leading downward to and connected with the receptacle.

2. In a lubricator, the combination with the journalbox, and a lubricating-block of a receptacle for the block fitting loosely within the box, springs secured to the sides of the receptacle and contacting with the side walls of the box for centering it laterally therein, springs resting upon the box, and rods supported by the springs and leading downward to and connected with the receptacle.

3. In a lubricator, the combination with the journal-box, and a lubricating-block of a receptacle for the block fitting loosely within the box and having ears provided with openings, springs on the box, and rods supported thereby and leading downward and removably engaging said openings.

4. In a lubricator, the combination with I the journal-box, and a lubricating-block of a receptacle for the block fitting loosely within the box and having ears provided with openings, springs on the box, a cross-piece mounted on said springs, and rods supported thereby-and leading downward and removably engaging said openings.

5. In a lubricator, the combination with the journal-box, and alubricating-block; of a receptacle for the block fitting loosely within the box and having ears provided with outwardly-opening notches, springs on the top of the box, and rods supported thereby and. leading downward into the box and having headed lower ends removably engaging said notches.
